Amyris. octanuria monogynia. 247 



ers in May. Leaflets petioled, oval, or ovate, taper-point- 

 ed, entire, polished ; about three inches long and about 

 two broad. Petioles nearly as long as the leaflets, round, 

 polished, and coloured. Stipules none. Peduncles axilla- 

 ry and Irom the base of the tender shoots below the young 

 leaves, as well as from the apices of small lateral, 

 leaflets scions; often as long as the petioles, diverging, 

 three-flowered, or once, or twice dichotomous, and ma- 

 ny-flowered. Flowers small, yellow. In Bengal they 

 have hitherto proved abortive. Bractes in opposite pairs, 

 at the divisions of the peduncles, lanceolate, smooth and 

 fleshy. Calyx four-toothed, half the length of the petals. 

 Petals four, linear-oblong, their lower two-thirds forming 

 a tube, the upper third expanding, and acute. Filaments 

 eight, shorter than the germ, alternately longer, inserted 

 on a fleshy ring round the base of the germ. Anthers 

 ovate-sagittate, apparently destitute of pollen. Germ 

 ovate-oblong, clammy, two-celled, with two ovula in 

 each, attached to the partition below the middle. Style 

 scarcely any. Stigma large two-lobed, and these again 

 somewhat two-lobed. Fruit not seen. 



The Bark and all the tender parts of the plants, on be- 

 ing bruised or wounded, discharges a small quantity of a 

 pale whey-coloured liquid, which possesses a fragrance 

 something like that of the orange leaf. 



In Bengal the flowers constantly prove abortive. I 

 therefore conclude the tree to be polygamous, and that 

 ours are all female-hermaphrodites-, with imperfect sta- 

 mina. 



When the trees were younger, the leaflets were more 

 numerous, often five and sometimes seven; I then thought 

 it might be Amyris Protium, but have now reason to 

 think it a new species.
